   A soil profile is a vertical cross section of soil that is dug approximately 3-5 feet deep to expose the various layers of the of the soil. The physical and chemical differences between the six soil horizons are developed from the interaction of five soil-forming factors.

   What is a soil profile?

   • The arrangement of these horizons in a soil is known as a soil profile. Soil scientists, who are also called pedologists, observe and describe soil profiles and soil horizons to classify and interpret the soil for various uses. Soil horizons differ in a number of easily seen soil properties such as color, texture, structure, and thickness.

   How do soil scientists identify master horizons?

   • Soil scientists use the capital letters O, A, B, C, and E to identify the master horizons, and lowercase letters for distinctions of these horizons. Most soils have three major horizons -- the surface horizon (A), the subsoil (B), and the substratum (C). Some soils have an organic horizon (O) on the surface, but this horizon can also be buried.

   What is soil composed of?

   • Soil consists predominantly of mineral matter, but also contains organic matter (humus) and living organisms. The pore spaces between mineral grains are filled with varying proportions of water and air. Figure 9.2.1 9.2. 1. Soil Profile. Photograph shows a soil profile from South Dakota with A, E, and Bt horizons.
